embodying the construction shown and described in U. S. Letters Patent,No. 1,658,400, dated February 7 1928.

The thread-guide 4 is mounted at the front of the drive-roll 2 to adaptit to reciprocate longitudinally thereof. As shown in Fig. 2 thethread-guide 4 projects upwardly from a slide 14 which is slidable on ahori zontal bar or rod 15. A second horizontal bar 16 is engaged by ahooked bearing 17 on the back of the guide to maintain the latter inerect position it slides on the rod 15. The rod 15 and bar 16 aresecured in place at the front of the machine by means of suitablebearingblocks 18, see Fig. 1, w ich clamp them against the vertical arms19 forming a part of the frame-mem- The slide 14 is provided with a lug22 through which extends a stud 23 carrying a bowl or roller 24 at itslower end which engages with the helical groove 25 in the cam 5. The cam5 is carried on a continuously rotating shaft 27 which extendsthroughout the length of the machine frame to operate the cams for otherwinding units mounted thereon. The rotation of the cam 5 causes theguide 4 to reciprocate back and forth at the front of the driveroll 2,and the upper end of the guide is inclined inwardly toward the point ofcontact of the cop with the periphery of the drive-roll and providedwith a suitable thread-grove 28 through which the strand z leads todirect it onto the cop. The

above described instrumentalities constitute the essential elements ofthe winding mechanism of the machine and are similar in generalconstruction and arrangement to those heretofore employed in the art.

It has been noted that as the cop or cone builds up on the holder 3 thelatter swings upwardly with its supporting arm 10, and suitabledogging-means are usually provided for steadying the motion of theconedepends from the swinging arm 10.

holder and preventing a retrogressive movement thereof. In the presentinvention the dogging-means comprise an improved construction over thatdescribed and illustrated in the prior application first referred to. Asin the prior invention, the doggingmeans is adapted to cooperate withthe stopping-mechanism of the machine to arrest 'the winding operation,but in a somewhat different manner. In the previously shown constructionthe dogging mechanism comprises an arcuate slide or quadrant 30 whliicheferring to Fig. 1, the quadrant 30 is held in an arcuate slot 31 on theside of the arm 10 and is clamped in position by means of a bolt 32 andwasher 33 overlying its side. Through this arrangement the quadrant 30,which is employed as a slidable element for actuating thestopping-mechanism, may be adjusted in the slot to regulate the extentto which it projects below the arm 10, this adjustment providing forsetting the quadrant to trip the stoppingmechanism when the arm 10 hasbeen moved upwardly to a predetermined extent in accordance with thediameter of the cop or package to be wound. This same arrangement of thequadrant 30 is employed in the present construction.

The dogging-means which cooperate with the quadrant 30 to actfrictionally thereon to prevent retrogressive movement of the arm 10comprises the previously disclosed sliding rod or bar 35 which alsoforms the trippinganeans or trigger for the steppingmechanism. As shownin Figs. 1 and 2, the slide or bar is mounted to slide through a slottedbearing 36 formed on an arm or extcnsion 37 of the bracket 12. The slideor bar is provided with two longitudinal slots 38 which are engaged bypins 39 and 40 to hold the slide in suspension; the rearward pin 39being driven through the sides of the slotted bearing 36 and the forwardpin 40 projecting from the side of the bearing-block it; previouslydescribed as fasned to the arm 19 of the frame-member 6. Instead ofarranging the slide 35 to bear directly on the quadrant 30 to effect thedog gin g-action, as in the device of the prior application firstreferred to, in the present invention the dogging-means is constitutedas a separate element connected to be operated from the slide. As shownin Figs. 1, 5 and 8, the extension 37 of the bracket or frame-member 12has an arm 41 extending upwardly therefrom and carrying a pin 42 fast inits upper end. Pivoted to rock on the pin 42 is a bifurcateddogging-element or lever 43, shown in detail in Fig. 7 arranged with itsopposite arms 44 straddling the sides of the quadrant 30, see Figs. 5and 8. The lower end of the dogging-member 43 is offset slightly to abutthe side of the slide 35 and is provided with a lip 34 at the bottomadapted to engage a slot 26 on the under side of the slide. The two arms44 of the dog 43 are connected by a cross-strip 29 having its edgebeveled to adapt it to act as a shoe engaging against the convex face ofthe quadrant 30 as shown in the detailed View, Fig. 9. Through thisarrangement the fixed pin 42 engages one side of the quadrant'and thecross-strip or shoe 29 bears against the opposite side so that when the,dog is rocked on the pin 42 it will exert a frictional binding actionon the quadrant to resist the downward sliding movement of the'latter.This actionprevents retrogressive movement of the copholner after thelatter has been forced upwardly by the growth in the winding.

The dog 43 is rocked to effect the frictional gripping action throughthe sliding movement of the slide 35 connected to its the trip for thelower end by means of the lip 34 and. slot 26, the slide being under theinfluence of resilient means such as the spring-45'. The spring 45surrounds against the rearward side of the bearing 36 with its oppositeend pressingagainst a pin 46 driven through the slide. The spring 45thus acts to, adjust the slide rearwardly with respect to the front ofthe machine to rock or tilt the dog 43 to press the beveled face of itsshoe'29 against the convex face of the quadrant 30. The dog thus actsboth to resist the upward swinging movement of the arm carrying thecop-holder 3 and to more positively check retrog-ressive movement of thearm in the manner as before explained. The movement of the coneorcop-holder 3 away from the driveroll 2 is thus more efficientlycontrolled to provide a smooth, vibrationless motion whereby the cop orcone is prevented from jumping or rebounding with respect to thedrive-roll during the winding operation.

It has been stated that the slide 35 acts as stopping-mechanism of themachine, the engaging portion or'shoe 29 of the dog 43 being adapted toslide ofi from the end of the quadrant 30 after the package has reacheda predetermined diameter in accordance with the adjustment of thequadrant on the arm 10. The instrumentalities which cooperate with theslide to arrest the winding operation are illustrated in detailin Figs.2 to4 andwill benext ex-,v plained. To arrest the rotation of the coporcone-holder 3 the arm 10 is lifted to re move the package from'contactwithfthe.

practice'in ma: The lifting of drive-roll 2 as is the usual chines ofthe present type.

the cone-holder 3 is accomplished by positively raising the arm 10through the means of a ratchet-mechanism, shown in detail in Figs. 5 and6, which acts on the quadrant 30. It will be noted from these views thatthe quadrant 30 is formed with ratchet teeth 49 on its rearward side asviewed in Figs. 2 and 4. Adapted to engage the teeth 49 on the quadrant30 is a pawl 50 which is pivoted at 51 to a swinging'lever 52, see Fig.6. The pawl 50 has a tail-piece 53 acted upon by 'a plunger 54which isunder the pressure of a spring 55 heldin a pocket depending from thelever 52. The spring55 maintains the pawl 50 in engagement with theteeth 49 and, preferably,-the bearing of the pawl on its pivot 51 ismademore or less loose to provide play so that the pawl may adjust itself tothe teethwhen the quadrant 30 is moved a distance less than the lengthof a tooth.

The lever 52 is fixedly secured to the end of a rod 56 which is rockablymounted in a bearing57 forming. a part of the arm '37 on theframe-member 6 as shown in Fig. 2.

F: The rod 56 has a second bearing 48 at the the slide 35 and is held,

front of the. frame-,member 6ias' shown in Fig. 1. The rod 56 also formsthe lock or et t anism normally inactive, itsforward end being bent intoa crook at 5 8 and terminat ing in an inclined arm 59 fori'ned with apointed detent-blade 60, see 8, ,The detent-blade 60 is adaptedto engagea notch or shoulder '61 on a latch-plate 62 which is fastened to the topof a post 63 projecting upwardly from arockable member 65, shown in Fig.2 and later described. The latch-plate 62 is adapted to be rocked intothe position shown by dotted lines in Fig. 8, whereby the detent-blade60 is released from the shoulder 61 to cause it toslide along theinclined edge 64 of. the plate 62 in the mam ner and 'for the purpose ashereinafter eX-. plained. The release of the detent-blade 60, permitsthe rod 56 to be rocked under the infiuenceof a spring 67 which isanchored to the frame-member 6, see 9 per end engaging the hooked end 68of an arm 69 on the lever 52, see also Fig. 6. A stop-screw 70 screwedthrough the arm 69 and locked in placeby a checknut 71 is adapted tostrike against the top of the arm 37, see Figs. 1 and 5, to limit therocking-' motion of the lever 52 under the action of the spring 67.\Vhen the detent-rod 56 is released the spring 67 will rockthe lever 52carried thereon to lift the pawl 50 to a certain extent as regulated bythe adjustment of the stop-screw 70. The lifting of the pawl 50 in thismanner acts through the ratchet on the quadrant 30 to slide the latterupwardly whereby toraise thearm 10 to lift the package, indicated at Yin Fig. 2, out of contact with the drive-roll 2 to arrest; the windingoperation. It will thus be apparent that the lever 52, the pawl 50 andthe spring'67 constitute the means hereinafter referred to as thestopping mechanism for arresting the operation r I the machine.

It has been noted that .the threadsguide 4 is reciprocatedcontinuouslyfand there,- fore 'as' the cop oncone is lifted away'fro mthe drive-roll. 2 to arrest the winding opera;

tion it is desirable that the strandfz be refor maintaining thestopping-moch Fig.1, with its upmovedfrom'the guide to preventithe' yarnor thread from being. cut or broken. The rockable member '65, previouslydescribed as carrying the latch-plate 62, constitutes the thread-lifterfor disengaging the strand 1 from the thread-guide 4. As, shown in Figs.2 and 4, the thread-lifter 65.- is constructed in the form of arelatively flat plate provided with suitable trunnion bearings on themain frame of the machine. Referring to Fig. 4, the thread-lifternormally assumes a position with its upper edge at the rear of and belowthe guiding-groove 28 in the thread-guide 4, being retainedin thispositionby the engagement ofthelatchplate 62 with the detent-blade 60 onthe rockable rod 56. The thread-lifter 65 is rocked into the position.shown in Fig. 2 to release the detent-rod 56- and to act concurrently tolift the strand y out of the groove in the thread-guide 4 in the manneras later explained. This action of the thread-lifter is effectedthroughthe cooperation of instinmentalities as next described.

Referring to Figs. 2, 3 and 4, a bifurcated lever 77 is pivoted to thepin 40 which supports the forward end of the slide 35, the opposite legsof the lever being straddled across the slide. The lever 77 has anelbowshaped arm 78 which is formed with an inclined slot 79 engaged by apin 80 projecting from the side of the slide 35. "When the slide 35 isslid into the position shown in Fig. 3, under the pressure of the spring45, the pin 80 slides in the slot 79 to tilt the elbow-shaped arm 78 ofthe lever 77 upwardly. The end of the arm 78 of the lever 77 is hookedunder a crank-arm 81 which, as shown in Fig. 2, forms part of a wire rod82 pivotally mounted in lugs 83 on the under side of the thread-lifter65. The crank-arm 81 has a hook 851 at its end to which connected a wirelink 85. The link 85 is hooked beneath the tail-piece 86 of a knockofflever 87 which is pivoted on a pin 89 projecting from the side of alever 90. The lever 87 has a bifurcated portion 88, the sides of whichstraddle the lever 90. The lever 90 is pivoted on a pin 91 driven intothe side of the frame-member 6 and its upper end is bent over at 92 toadapt it to engage a tailpiece 93 projecting at an angle from one of thebearings of the thread-lifter 65. The tail-piece 86 on the lever 87projects into position to adapt its end to be engaged by a going elementof the machine, such as the toothed collar or wheel 95 which is securedto the cam-shaft 27 to rotate therewith. it pin 96 projecting'from thesideof the ma chine frame limits the upward movement of the tail-piece86 of the lever 87 whereby when the end of the tail-piece is engaged bya tooth on the wheel 95 the lever will be moved bodily to rock theconnected lever 90 in the direction indicated by the arrow in Fig.3.This rocking action of the lever 90 brings its bent portion 92 againstthe tailpiece 93 on the thread-lifter 65 to rock the latter toraise thethread out of the threadguide'while releasing the detent for thestopping-mechanism in the manner as hereinafter more fully explained.

The lever 87 may also be rocked to engage its tail-piece 86 with thetoothed wheel 95 to arrest the winding operation when the strand breaks,a suitable breakage-lever 125 shown'in Fig. 4 being employed for thispurpose. The breakage-lever 125 extends outwardly from the rod 82 and isadapted to rock said rod when released from the strand y. The lever 125acts in the manner explained in the previous application to raise thearm 81 to cause it to act through the link 85 to lift the tail-piece 86of the lever 87 into position to be engaged by the rotating collar orwheel 95 in the manner as shown in Fig. 3.

'Referring now to Figs. 2, 4i and 8, the detent-rod 56 carries a lever128 having its hub abutting the side of the bearing 57 and secured fastto the rod by means of a binderscrew 129. The lever 128 has abevel-sided lug 130 at its lever end which is adapted to co-act with theinclined side of an upright arm or cam-plate 131 fastened to the slide35. As shown more particularly in Fig. 8, the cam-plate 131 is rivetedto the rearward side of the bar slide 35 at 132 with its arm reachingupwardly therefrom and outwardly in front of the rockable rod 56. At itsupper end the arm is extended in a nar row portion or finger 133 adaptedto bear against the side of the rod 56 to take the thrust of thecam-plate 131 when the latter is acted upon by the lever 128. As shownin Fig. 8, the cam-plate 131 is bent to form the inclined face 134against which the beveled lug 130 engages when the lever 128 is rockedwith the rod 56. The lever 128 will. thus effect prying action on thecamplate 131 to slide the slide 35 to the left as viewed in 2 againstthe action of its spring 41-5. The purpose of this arrangement, which isa feature of improvement Over the mechanism described and illustrated inthe patent first referred to, is to release the knock-off lever 87 fromengagement with the toothed wheel 95 after the operation of the machinehas been arrested. That is to say, after the knock-olf lever 87 has beenlifted to engage its tailpiece 86- with the rotating wheel 95 and thestoppingmechanism has functioned it is desirable to release theknock-off lever so that it will not be continuously actuated and causedto chat- .ter under the intermittent engagement of the teeth with itsend. The slide 35 is slid to the left to slide the pin 80 in theinclined slot 79 in the lever 77 whereby to release the lever 87, thisaction being more fully explained in the method of operation of thecomplete machine.

lllanually-operable means are provided for releasing the ratchet toreturn the coneholder 3 into driving connection with the drive-r0112 andto concurrently reset the stopping-mechanism to start the windingoperation. This manually-controlled means also operates to return thethread-lifter to normal position and the instrumentalities employed forthis purpose are illustrated in Fig. 1. They comprise, essentially, abifurcated frame pivoted on the trunnionpins 7 5 which support thethread-lifter 65. Bolted to the depending portions of the inc engage itsframe 100 is a curved handle or startinglever 105 which reachesoutwardlyfrom the front of the .machine 'in convenient position to begrasped by the operator. 7 Referring to Fig. 4, one end of-the frame:100 isextended upwardly inan inclined arm 106 which normally liesadjacent and in valinement with the main portion of the thread-lifter+65. The arm 106 is curledover at the top in an extension 10.8,.see'Fig. 4, .which is adapted to engage beneath the crooked portion 58 ofthe 'detent-rod 56 to rock-the latterto detent-blade .60 with thelatchplate 62. The arm 106 of the frame 100 is also provided with .aweb-like extension 109 which is engaged .by :the shocked end 110 :of theslide 35. It will thus be observed that when the starting-handle105 isdepressed into the position illustrated in Fig. 4 the frame 100 will :berocked to cause its arm 106 to slide 35 1'60 move :the' dog 43 intoposition .to adapt the quadrant to slide I Dun down against the shoe 29on the dog. ing this operation the finger or extension 108.011 the arm106 rocks the detent-r-od 5.6 to engage its blade 6Q'Wlth thelatch-plate 2 and this rocking .motion of the rod 56 also operates torock the lever 52 to release the pawl 50 from the ratchet-teeth on thequadrant 30, the functioning of these parts .to start .thewindingoperation :being more fully. explained hereinafter."

A spring 111 normally holds the frame 100- in the position illustratedin Fig. 1 with its extension 108 bearing against a lug or rest 11-2 onthe bearing-block 18. The spring 1111 is connected at 113 to the frame100 with its-opposite end anchored to a pin 114' held in the'side of theblock18. I

Referring again to Fig. 4, a bell-crank lever 115. is pivoted on the pin91 which forms the pivotal support for the l'everg90 and one of its arms116 reaches upwardly and is bent over in a finger 117 which engagesthrough a hole 118 in a lug 119 011 the frame 100. The lower arm 120 ofthe lever 115 isadapted to engage the tail-piece 86 of the lever 87todepress its free end from the teeth on the wheel 95, the lever 115being rocked to efiect this action as shown in Fig. 4 when thestartinglever 105 is depressed to start the winding operation. Themethod ofOperationof the complete machine is as follows: p

. Assuming that the windinghas been a-rrested with the copor cone-holder'3 held in raised position above the drive-roll "-2 through the means ofthe ratchet-mechanism shown in Figs. 5 and .6, the machine is preparedfor operation by placing a paper shell or tube T on the mandrel orholder. The strand 3/ .of yarn or thread is drawn up from its source ofsupply, not herein shown, and led under the breakage-1ever125,

thence across the upper edge of the --threa-dthe latter to hold lifter.65 and its. end secured to the cone- With the .machineat rest the parts:of the stopping-mechanism arein position s'ubstan- I itia' llyasshownin Fig.2. To start :the windingthe oneratorgrasps the startingdever 105and presses ii t downwardly to the position illustrated in Fig. 4. Thisaction rocks the frame i100, and the latter acts through its drawn backinto the position shown in Fig.

4 so that the shoe 29 on thedog 43 is moved .back to clear the'ilowerend of the:quadr'ant 30. As soon as the slide hasbeen withdrawn in thismanner the further movement :of the rocking frame 100 causes itsextension 108 to engage the :crook or crank '58 at the end of the rod 56to turn .the latter to rock the lever 52 .carried at its end, The lever.52 is thus rocked against the tension of its spring 67, see Fig. 6,thereby causing the pin 4.7 .to act against the pawl .to release theflatter from :the teeth 49 :onthe quadrantc30. Immediatel-ythe pawl 50is released the arm 10 will swing downwardly'ito lower the coneholder 3to bring the surface of the coptube carried thereon into contact withthe periphery of :the continuously rotating dTdVBfl'Oll 2-. The contactof the cop-"tube with the drive-roll will therefore cause the cop-holder.tobe rotated therefrom in the die rection indicated by the arrow inFig. 4." As the cone-h-olderlis lowered against the driveroll 2 thequadrant 8O slides downfiinto position to adapt :the shoe-29 on the dog'43 to 1 r be frictionally engaged with its convex .Surface after .theslide 35 has beenreleased to allow it to slide rearwardlyunder theaction of its spring 45. This release ofthe slide 35 does not takeplace', however, until the starting-lever has been released by the.joperator. [Previous to this release of the sl de, 35 the downwardmovement of the .lever- 105, and the rocking action of the frame 100,causedthereby, acts through the bell-crank lever to cause the arm ofthe latter 'topressthe, tail 86 of theil'ever .87 downwardly to removeit from possible contact with the toothed wheel 95. "This ac- 'tionofthe bell-crank lever 115 thus serves to prevent unwarranted arrest'ofthe windmg operation .whi'le the strand y of thread or yarn is slack andthe breakage-lever dropped so that it will not free the lever 87 ,or, inother words,lower it away from the toothed wheel 95.

Itshould be stated that when the thread lifter 65 is first tilted orrocked upwardlythrough the action of the lever 90 it is held inthisposition as shown in Fig. 2 by means "of the blade 60 of the detent'rod5,6 which slides alongthe iilclined edge 64 of the detent p1ate62to theposition shown in dotted into the position shown in Fig. 4 under theaction of gravity. At this point the blade 60 on the detent-rod 56 iscarried into engagement with the detentsl1oulder 61 on the plate 62, seefull lines in Fig. 8, and this action causes the stopping-mechanism tobe locked in inoperative position. The

' .dropping of the thread-lifter 65 permits the strandy of thread oryarn to ride across its upper edge in such relation to the thread guide4 that it will be picked up by the guide to seat it in the groove 28 asshown in Fig. 1. This automatic threading of the thread- .guide takesplace as the guide recipro-cates across the path of the thread in themanner as explained in the patent before referred to. Asthe strand 3 ofyarn feeds to the rotating cone-holder or winding-mandrel 3 its slack istaken up and the breakage-lever 125 is suspended thereby to prevent itfrom influencing the knock-off lever 87 to cause arrest of the windingoperation. The operator can now release the starting-lever 105 and theframe 100 will be returned to normal position as shown in Fig.1 underthe action of its spring 111. With the parts of the mechanism set inthis relation the winding opera tion will continue with the threadguide4 traversing the strand :1 back and forth lon- .gitudinally of thecone-holder 3 to direct it onto the cop-tube T.

\Vhen the strand y breaks or its supply is exhausted the breakage-lever125 drops and raises the tail 86 of the knock-off lever 87 into theposition shown in Fig. 3 to operate the stoppinganechanism of themachine in the manner as previously explained. Likewise, when the conereaches a predetermined diameter the stopping-mechanism low thedog ofthe rod will thereby act arm. 81 and link 85 to lift is released throughthe disengagement of the quadrant 30 from the shoe 29 on the dog 43 in.the manner as next explained. As the quadrant 30 is carried up with thearm 10 its end finally rides off. from the shoe 29 toal- 43 to rock onits fixed pivot 42. This permits the rod 35 to slide to the right underthe action of its spring 4:5 as shown in Fig. 3 and the pin 80 at theopposite end through the slot 79 in thelever 77 to rock the elbow-shapedarm 78 of the latter upwardly. The lever 77 isthus caused to act throughthe crank Y the tail 86 of the knock-off lever 87 to bring it intoposition to be engaged by the teeth on the wheel 95. The rotation of thewheel 95 will therefore cause the knock-off lever 87 to rock the lever90, acting through the tailpiece 93 on the thread-lifter to tilt thelatter up wardly to withdraw the strand 3/ of thread or yarn from thetl'iread-guide 1.

As before explained, the raising of the thread-lifter 65 releases thedetent-shoulder 61 on the plate 62 from the blade 60 at the end of therod 56, allowing said rod to be rocked under the action of the spring 67connected to the lever 52. The rocking of the lever 52 acts through thepawl 50 to force the quadrant 30 upwardly, whereby the arm 10 is raisedto lift the cone-holder 3 to remove the cop or cone from contact withthe periphery of the drive-roll 2, as shown in Fig. 2. The rotation ofthe coneholder 3 is thus arrested and the strand y of yarn or threadreleased from the threadguide 4: so that the winding operation ceasesuntil the stopping-mechanism is manually operated again in the manner aspreviously explained. It has been noted the the blade 60 on the rod 56slides along the beveled edge of the detent-plate 62 to the positionshown by dotted lines in Fig. 8 to act as a holding-means to maintainthe thread-lifter 1n ra1sed position unt1l the winding operation isstarted again, and in this way the machine is maintained inoperativeuntil prepared to wind again.

It has also been explained that after the slide has been moved to theright under the action of its spring 15 to arrest the operation of themachine, the slide is slid back again to tilt the lever 77 downwardly soas to remove the tail 86 on the lever 87 from contact with thestopping-Wheel 95. This last action is effected through the operation ofthe lever 128 on the cam-plate 131 as the rod 56 is rocked by the spring67, after its blade 60 is released from the shoulder 61 vholder awayfrom the driving-drum shall be properly regulated for the purposedescribed.

While the present improved controllingmeans and stopping-mechanism isherein shown and described as applied to use with a certain type ofmachine, and as embodied in preferred form or construction, it is to beunderstood, that various modifications may be made in the structure andarrange ment of the partsof the device without departingifrom the spiritor scope of the in,-

, vention. V
